Abstract

A load-support structure of a canopy or like construction has an upright column 1 jointed to a horizontal roof-support member 2. An aluminum alloy block 9 is received within the cavity 5 of member 2 and has a transverse bore 10 and an axial bore 11. Cavity 9b is defined by block 9 in cooperation with wall 5b of member 2 and houses a block 12 having a screw-threaded bore in register with bore 10. Screw 13 penetrates both bores and screws into the bore in block 12. Screw 16 engages in bore 11 and is axially displaceable for adjustment purposes. The head of screw 16 is received in cavity 7 of column 1. Operation of screw 13 displaces block 12 and by reaction causes displacement of block 9 to effect engagement of the head of screw 16 with column 1 in assembly of the structure or disengagement for dissassembly purposes. Relative rotation is prevented by pin 18. <IMAGE>

Description

Improved Joint for Aluminium Extrusions The invention relates to an Improved joint, particularly, but not exclusively, for aluminium extrusions such as used In canopies and other roof structures where a framework of members supports a roof substrate, furniture, shelving, racking and In horticultural structures such as fruit cages and greenhouse staging.
Aluminium extrusions In a wide variety of configurations are a popular material in which to construct the framework of such buildIng structures as conservatories and car ports. Once such a framework is constructed, a roof substrate, usually In the form of glazing panels, Is supported upon upwardly-facing surfaces and, of course, glazing panels are provided as windows upon vertical surfaces. The framework usually comprises a number of upright columns which support a plurality of substratesupport members usually with a marked pitch to ensure run-off of surface water. In the case of a conservatory, for example, a wall of an existing building structure, typically a domestic house, is sometimes used to support one end of the substrate-support members.The pitch of the members provide an InclIne down from the wall to a fixture point where each substrate-support member Is joined to an upright column, gutterlng being provided near the junction to receive water running off the inclined substrate of the finished structure. Whilst aluminium extrusions are perhaps the most popular material for structures of this kind, It has long been recognized that real problems exist in joining the upright columns to the substrate-support members. This problem exists to some extent where the two elements of the structure join at right angles but It Is much more marked In the case of structures (eg car ports and conservatories) where the upright columns and the substrate-support members join at an angle of less than (or more than) 900.
According to the invent ion, there Is provided a structure for use in load-support and comprising elongate members connected together, said structure comprising at least one sub-assembly which comprises a first elongate member and a second elongate cooperative member, one of said first and second members being provided with a slot and the other one being provided with a mounting assembly which is cooperative with said slot and which comprises a fixture member configured for admission through an entrance to said slot and shuttle means displaceable axially within a bore of said other one of said first and second members to displace said fixture member between a first position In which It Is engaged with slot-defining surfaces of the slotted member for retention in said slot in assembly of the sub-assembly and said shuttle is of fixed position and a second position in which said fixture member is disengaged for displacement from said slot in disassembly of the sub-assembly.
The invent ion In particular provides a bulling structure wherein a roof substrate Is supported by cooperation of substrate-support members and load-bearing cooperative members to which said substrate-support members are mounted, said structure comprising at least one subassembly which comprises an elongate substrate-support member and an elongate load-bearing cooperative member, one of said elongate substrate-support member and said elongate load-bearlng cooperative member being provided with a slot and the other one being provided with a mounting assembly which Is cooperative with said slot and which comprises a fixture member configured for admission through an entrance to said slot and shuttle means displaceable axially within a bore of said other one of said substrate-support member and said elongate loadbearing cooperative member to displace said fixture member between a first position in which it is engaged with slot-defining surfaces of the slotted member for retention in said slot In assembly of the sub-assembly and said shuttle is of fixed position and a second position in which said fixture member Is disengaged for displacement from said slot in disassembly of the subassembly.The substrate support member Is preferably not supported by the load-support member other than through said mounting assembly and in any event will preferably be Inclined with respect to the load-support member.
The term "bulldlng structure" as used herein is used in a very general sense and includes such structures as conservatories and car ports as well as a variety of other arrangements in which a canopy is supported offground. Similarly, the expression "roof substrate" is also used in a very general sense and is typically exemplified by glazing panels supported in a generally upwardly-facing orientation as well as by similarly disposed non-transparent substrates such as plastics sheeting. The expression "glazing panel" just referred to Is intended to include not only panels of glass but sheet glass per se as well as framed and unframed transparent sheet material such as polycarbonate, (meth) acrylic resin sheeting and similar materials.
The elongate members referred to may be made of any of a variety of materials such as timber and metallic materials but the invention is primarily directed to arrangements In which these elongate members are in the form of extrusions made of aluminium or aluminium alloy.
Whilst the elongate members may be joined to each other perpendicularly, the invention is primarily -of value In providing a jointing arrangement In which the two may be joined other than perpendicularly. In a typical such arrangement, a first elongate member will be inclined to horizontal by an angle of from 5 to 450, for example 10 to 400, a pitch of 15 to 350 such as about 300 being fairly typical. In the case of a building structure, the pitch will generally provide an incline down which surface water may run in a direction toward the load bearing cooperative members referred to earlier but the elongate substrate-support members may be InclIned with their pitch in the opposite direction.
Preferably, the first elongate member of said subassembly Is provided with said mounting assembly and said second elongate member Is slotted.
The second elongate load-bearing cooperative member of said sub-assembly is conveniently a column which has said first elongate member mounted thereto.
The one of said elongate members provided with said mounting assembly is preferably of hollow tubular construction.
The mounting assembly of said sub-assembly may comprise shuttle means displaceable by reaction between said shuttle means and a motion-transfer element.
The shuttle means is conveniently displacable axially within said bore by displacement of said motion-transfer element perpendicularly with respect to the axis of displacement of said shuttle means.
The shuttle means and/or the motion-transfer element have reactive oblique surfaces in preferred forms of the invention.
The motlon-transer element Is conveniently displaceable upon a shaft.
The shaft is preferably externally screw threaded and said element Is internally screw threaded and received over said shaft In threaded engagement therewith.
The shaft may be exposed for manipulation from outside said bore of said one of said elongate members as is provided with said mounting assembly so as to enable said element to be displaced to cause axial displacement of said shuttle means.
The fixture member generally comprises a shank having an enlargement responsible for retention of said fixture member within said slot of said sub-assembly. The shank is preferably threaded and is threadedly engaged with the shuttle means. The shank preferably has an axis parallel to or coincident with the axis of displacement of said shuttle means.
According to preferred embodiments of the invent ion, a structure comprises at least one sub-assembly which comprlses:- (I) a column formed with a lengthwise slot; (II) a tubular member, typically (in the case of a bul iding structure) a substrate-support tube; (iii) a shuttle disposed within said substrate-support tube; (Iv) a headed elongate member secured to said shuttle and extending from an axial end opening of said substrate-support tube and Into said slot; and (v) a displacement screw penetrating the substrate support tube and threadedly engaging a motion transfer element within the tube, said screw being operable to displace the shuttle axially within the cavity of the tube by causing displacement of said element in a direction perpendicular to the axis of displacement of said shuttle, so that said head of said headed elongate member can be engaged in and disengaged from said slot to secure the substrate-support tube and column together or to loosen such securemet to enable disassembly.
In a second aspect, the invention provides a method of constructing a bu I iding or other structure as defined herein which method comprises mounting said first elongate member to said second elongate member to construct said sub-assembly by introducing the fixture member of the elongate member provided with the mounting means into the slot of the slotted one of said elongate members and displacing said shuttle means to engage said fixture member in said slot, constructing one or more further such sub-assemblles, securing said sub-assembiles In stable erected condition and supporting a roof substrate upon said elongate roof-support members.
The following Is a specific description Intended to Illustrate the invention, by way of example only, reference being made to the accompanying drawings in which: Figure 1 shows in vertical cross-section a roof structure in accordance with a first embodiment of the invention; Figure 2 Is a plan view, partially in cross-section, taken from the direction of the arrow 11 shown in Figure 1; Figure 3 Is a vertical cross-sectional view similar to Figure 1 but showing a second embodiment of the invent ion; Figure 4 Is a view similar to Figure 3 but showing a slightly modified form of the structure shown therein; and Figure 5 Is a view similar to Figure 1 but showing a further embodiment of the invent ion.
The building structure shown in Figure 1 of the drawings shows a sub-assembly of a building structure in which an upright column 1 is jointed to a horizontal roof-support member 2. In practice, the building structure comprises a plurality of such sub-assemblles of similar structure.
Columns 1 and roof support members 2 are Identical extrusions of aluminium alloy, the horizontal cross sectlonal configurations of these members being represented by the sectioned portion of Figure 2 shown at the left hand side of that figure.
Accordingly, each aluminium alloy extrusion comprises two continuous non-perforated outer walls 3 and 4 defining an enclosed cavity 5 running the length of each respective member. The two remaining sides of the rectangular cross-section are represented by a more complex configuration defining a corner cavity 6 and a pair of channels or slots 7 and 8. It will be seen from the sectioned portion of Figure 2 that each slot or channel 7, 8 has an associated mouth 7a, 8a narrower than the corresponding dimension of the slot cavities.
Received within the cavity 5 of the roof-support member 2 is an aluminium alloy block 9 in the form of a cut-off portion of an aluminium alloy extrusion having the crosssectional configuation shown. Block 9 is formed with a generally central bore 10 and an external bore 11, and defines with the adjacent walls 5a and 5b of cavity 5 a pair of cavities 9a and 9b. A much smaller aluminium alloy block 12 is disposed in cavity 9b, block 12 having a central screw-threaded bore in which Is received the externally screw-threaded shank of a screw 13. As best shown in Figure 2, screw 13 is received through an enlargement of the mouth 8a, its head being seated on or Just above (depending on the adjustment position) wall 5a of cavity 5.It will be recognized from Figure 1 of the drawings that clockwise turning of screw 13 draws block 12 in an upward direction. This results in a reaction between oblIque surface 14 of block 9 and oblIque surface 15 of block 12 which causes block 9 to displace In the direction represented In Figure 1 by the arrow A.
A somewhat larger screw 16 has Its shank 17 received threadedly through bore 11 In block 9. The head of screw 16 is is turn received within cavity 7 of the upright column 1, as shown In Figure 1, the shoulders of the head being engaged against the Inner surface of those parts of the extrusion which define mouth 7a.
As represented in Figure 1 of the drawings, the head of screw 16 is tightly engaged against the Just mentioned mouth-defining wall portions of the extrusion so that the upright column 1 has the roof-support member 2 firmly mounted thereto. Any tendency of roof-support member 2 to rotate with respect to upright column 1 is resisted by pin 18 (normally made of stainless steel) which, as shown in Figure 1, has a portion received in a blind b-ore formed in block 9 and an opposed portion received through mouth 7a of slot or channel 7.
Construction of a sub-assembly of elongate members as shown In Figures 1 and 2 is a simple task which can readily be carried out without great skill or large expenditure of time. In practice, an elongate roofsupport member 2 may be factory assembled with block 9, block 12, screw 13 and screw 16 or, less usually, these components will be assembled to the elongate extruded aluminium alloy roof-support member In the field. Screw 13 Is adJusted so that the block 9 is approximately midway between the extreme displacements of Its reciprcity. The reciprocatory nature of the displacement available for block 9 is such that It will be appreciated that the block and its associated components perform the function of a shuttle.Each of channels 7 and 8 is open at Its opposed extremities to provide an entrance through which screw 16 may be admitted to the channel concerned, once admitted the screw having Its shank 17 received through the mouth 7a, of slot 7 whilst the head is retained within the cavity of the slot adJacent to the marginal edges of the mouthdefining portions of the extrusion wall. By judgement and trial-and-error, screw 11 may be adjusted so that it may be admitted to channel 7 as an easily manipulable although reasonably tight fit. The elongate roofsupport member 2 is In this way provisionally mounted to the column 1 and can be slid along a track represented by channel 7 to any desired point.When the point desired for the elongate roof-support member 1 has been located, screw 13 is turned in a clockwise direction. Turning of screw 13 In this way draws block 12 onto the threaded shank of screw 13 and brings the oblique surface 15 of block 12 Into sliding contact with the oblique surface 14 of block 9. Continued motion of block 12 axially upon the shank of screw 13 gradually urges block 9 in the direction represented by the arrow A In Figure 1. It will be appreciated from the Figures that this movement of block 9 draws screw 11 upon a path of displacement parallel to the axis of the cavity 5 of elongate roof-support member 2.This gradually seats the head of screw 16 firmly against the Internal surfaces of the outer mouth-defining wall of the aluminium extrusion of column 1 until a tight and secure fit is achieved and the elongate roof-support member 2 Is capable of sustaining the load of a roof substrate, such as glazing panels or transparent or non-transparent roof sheeting material. The joint between the column 1 and the roofsupport member 2 is an aesthetically neat joint of the kind so desirable In the building structures to which this invention is intended to be applied. The joint is constructed of simple readily available components which cooperate to provide a reliable joint.The joint can In addition readily be disassembled by counter-clockwlse turning of screw 13, the resulting right-left movement of block 9 then loosening the hold of the head of screw 16 upon column 1 so that roof-support member 2 can be slid to the top extremity of cavity 7 and separated from the column.
The assembly shown In Figure 3 of the drawings Is similar in almost all respects to the assembly represented in Figures 1 and 2 and like parts are designated with like reference numerals. In the case of the embodiment represented In Figure 3, however, roof-support member 2 is mounted to column 1 with a pitch of approximately 250 with respect thereto.
The arrangement shown In Figure 4 is virtually identical to that of Figure 3. However, It will be seen that a wedge-shaped washer 19 Is provided for load-distribution purposes between the head of screw 16 and the confronting surfaces of those parts of extrusion 1 which define mouth 7a of the slot. The surface of the washer 19 may be serrated on one or both sides thereof. A similar but flat washer may be provided in the arrangement shown in Figures 1 and 2.
Slots 7 and 8 may, of course, take a form other than the elongate linear form provided in the embodiments illustrated. One or both of the slots 7 and 8 may, for example, be a key-hole slot through the enlargement of which the head of screw 16 may pass but through the constriction of which It may not be admitted. For manufacturing convenience, of course, it Is preferred that both extrusions 1 and 2 be the same as then one die may serve to produce both extrusions needed for the building structure.
Assembly and disassembly of the joint represented In Figure 3 can be carried out in the same manner as in the case of the assembly shown in Figures 1 and 2 of the drawings. However, additional counter-clockwise turning of screw 11 will be required In order to extract screw 11 by a greater amount from block 9 to facilitate entry into the cavity of slot 7 at its upper terminal end whilst the roof-support member 2 and the head 16 of screw 13 are Inclined. The neatness and reliability of the joint between the roof-support member .2 and column 1 is substantially the same as In the embodiment shown in Figures 1 and 2.Despite the fact that the annular shoulder of the head of screw 16 has less of its surface area in engagement with the outer wall of the column 1 aluminium alloy extrusion, that part of the head which engages that wall Impinges somewhat into the surface of the wall In a compensatory fashion to provide security of fixture.
The arrangement shown in Figure 5 of the drawings is similar to that shown in Figure 1 and like reference numerals are used to designate like components. It will be seen that In this particular embodiment a horizontal roof-support member 2 is mounted somewhat differently to an upwardly extending member 1, in this case the latter being inclined with respect to the vertical. Whereas in the arrangement in Figure 1, a screw 16 has a shank 17 together with a head which is received within a channel 7 of the member 1, the arrangement In Figure 5 comprises a plate 16a engaged In channel 7. An arm 16c connects plate 16a to a solid cylinder 16b, arm 16c penetrating a slot mouth In the member 1 provided In somewhat similar fashion to the mouth 8a illustrated in Figure 2 of the drawings.The assembly comprising component 16a, 16b and 16c is a machined aluminium casting and it will be seen that a cylindrical socket 9a Is formed in block 9 to receive the cylinder 16b, the latter being introduced Into the socket 9a end-wlse along the longitudinal axis of the socket 9a. Both the socket and Its marriageable counterpart 16b have a circular cross-section such that rotation may take place. Rotation Is shown In Figure 5 as Limited by the points of engagement of the end of member 2 against the wall of member 1 and the configuration of the member 2 can be adapted to provide for a range of inclinations of member 1 with respect to member 2.
The invention as described earlier without reference to the drawings may include any one or more features of the invent ion as described with reference to the drawings.
